Is it possible to hit these times in a 99 Si? I know the turbo is a smaller one and was wondering how much power you could get out of it before running into efficiency problems. Also, how soon does the boost come on? Consider the setup with a fully tuned Hondata and 2.5 inch exhaust. How much boost could I run and what power would I put to the wheel? Thanks for any info. Also, anyone with a 99-00 Si and this kit, let me know. I would like to talk to you.

 

yes

 

Greddy... T25? T03? T04? smaller or larger than those? To answer some of the other questions you have, I'd have to know what size turbo you're talking about. SUPPOSEDLY, the Garret T03 stock in Z31's is maxed out internally at 18PSI, but I don't know that for a fact.

As far as spooling goes, that's what brake boosting is for..

 

Yeah, should be possible.. if not just turn up the boost

 

im not sure how pissible it is going to be, but youll definetely hit low 14s to high 13s on stock internals running 8psi with slicks.

 

I had a Civic Coupe that ran 12.80@107mph and on the street, my friend with a EK hatch ('99 Si swap, stock) with the GReddy 18G kit pulled on me with ease at 10psi.

Tons of potential.

 

Yeah, Im talking about the turbo that comes with the Greddy kit. How much boost can the turbo push before running out of steam? Also, how much boost can stock internals handle? Thanks again.

 

I ran 12.3 @ 111.11MPH on my GSR greddy kit.

 

Bump. Anybody have a Hondata setup recommendation for me?
